22、假设整型变量n,m,i已经声明和赋值，且大于n＞2.有如下运算规则:如果n是素数，m=0；否则，m=n。如下程序中正确实现此运算的是？A．m=n; for(i=2;i＜n;i++) if(n%i==0){ m=0;break; }B．m=0; for(i=2;i＜n;i++) if(n%i==0){ m=n;break; }C．m=0; for(i=2;i＜n;i++) if(n%i==0){ m=n;continue; }D．m=n; for(i=2;i＜n;i++) if(n%i==0){ m=0;continue; }
下面（）仅输出m的大于1的最小因子。A．for (i =2; i＜=m-1; i++) if (m % i == 0) { printf("%d is 最小因子n", i); break; }B．for (i =2; i＜=m-1; i++) if (m % i == 0) { printf("%d is 最小因子n", i); continue; }C．for (i =2; i＜=m-1; i++) if (m % i == 0) { printf("%d is 最小因子n", i); }D．i=2; while (m % i != 0) i++; printf("%d is 最小因子n", i);
下面（）是正确的判断素数程序（m＞1)。A．j=0; for (i =2; i＜=m-1; i++) if (m % i != 0) j++; if(j==m-2) printf(“%d是素数n", m);B．j=0; for (i =2; i＜=m-1; i++) if (m % i == 0) j++; if(j==0) printf(“%d是素数n", m);C．flag=0; for (i =2; i＜=m-1; i++) if (m % i == 0) flag=1; if(flag==0) printf(“%d是素数n", m);D．for (i =2; i＜=m-1; i++) if (m % i == 0) i=m+2; if(i==m+3) printf(“%d是素数n", m);
